Current association status is based on association status data in the internal storage that is stored in peripheral unit 18, between gateway 12 and the peripheral unit 18.If these data are zero, equal predetermined value, perhaps in the scope of predetermined value, then indicate peripheral unit 18 related with gateway 12; Otherwise this data indication peripheral unit 18 is related with gateway 12.
If current association status is related with gateway 12 at 46 indication peripheral units 18, then in step 48, whether peripheral unit 18 these disassociation frames of inspection are opened with definite communications slot and be can be used for peripheral unit 18 is associated with gateway 12.According to the embodiment of the invention, communications slot as known in the art, is meant the time interval that limits in the time division multiple access network.In addition, as known in the art, communications slot also refers to, for the desired service quality between the parts that guarantee wireless network, adopts the maximum node number that allows in the network of Carrier Sense Multiple Access or other access to netwoks schemes.In addition, in embodiments of the present invention, disassociation frame comprises connective marker, and described connective marker is corresponding to the corresponding communication groove and to identify this respective communication groove be available or unavailable.For example, in the network with 16 communications slots, 16 connective markers can be corresponding to the information (AT0 and AT1) of two bytes in the disassociation frame.The AT0 value remains 14 groove free time for but two grooves of 0x00 indicating head are unavailable for 0xC0 and AT1 value.In addition, for each connective marker, disassociation frame comprises ID part (that is, SN0, SN1, SN2...), with ID number of expression gateway appointment.In one embodiment of the invention, corresponding with unavailable communications slot and partly comprise nonzero value with the corresponding ID of the first available communication groove.If there is not open communication groove 50 to be used for peripheral unit 18 is associated with gateway 12, for example, when the value of AT0 and AT1 is 0xFF, it is full indication that peripheral unit 18 provides network in step 52, make attempting that peripheral unit 18 is associated with the operating personnel of gateway 12 or technical staff, to be apprised of network full, and this also indicates peripheral unit 18 not related with gateway 12.According to the embodiment of the invention, for the purpose of informing, peripheral unit 18 can comprise noise and form device, LED or other sighting devices, perhaps haptic device, the vibration unit of for example informing operating personnel by sound, light or haptic methods.In another embodiment, this informs it can is implicit expression, because after association is set up, successful association will cause in the outside still communication within communication range of nearby sphere.Be used to inform that other apparatus and method of operating personnel also are considered as dropping within the scope of the embodiment of the invention.After 52 inform that network is full, the peripheral unit timer be eliminated or forbid 53 and method 32 finish 54.
Refer again to step 48, if communications slot open 56 and can be used for peripheral unit 18 is associated with gateway 12, peripheral unit 18 transmits the related information bag in step 58 and replys gateway 12, and this related information bag is replied the number that comprises the local sign of its transducer (ID) number, its timer information and available communications slot.If the timer of peripheral unit 18 is section or the interior timer corresponding to gateway 12 of scope at the fixed time, then upgrade these disassociation frames and the disassociation frame that upgrades is sent to peripheral unit 18 at step 60 gateway 12.In one embodiment of the invention, gateway 12 upgrades disassociation frame by following operation: the transducer of the transducer local I being write disassociation frame for D number is confirmed (SNACK) part, upgrade AT0 or AT1 and become unavailable to indicate available communication groove by peripheral unit 18 identifications, be identified for non-zero gateway assigned I D by the groove of peripheral unit 18 identifications, write on the operation address (OPADR) of the message that exchanges during the operator scheme, write on the operating walk way (OPCHL) that uses during the operator scheme, and the timer information of new gateway 12 more.This operating walk way can relate to special carrier frequency, frequency pattern (pattern), be used for the code of code division multiple access or be used for sharing other mechanism of wireless medium.In one embodiment, operating walk way and operation address are unique for particular gateway device 12, and offer all peripheral units 18 in the gateway disassociation frame.
Peripheral unit receives and explains the disassociation frame that upgrades in step 62.If the timer of gateway 12 in preset range corresponding to the timer of peripheral unit 18, the data of peripheral unit 18 in the disassociation frame of this renewal of step 62 checking then.In one embodiment, peripheral unit 18 its transducer local idents of checking are stored in the SNACK.The timer of peripheral unit 18 is cleared or forbids in step 63, and peripheral unit 18 is informed the related success of operating personnel and gateway 12 in step 64.In addition, can imagine that peripheral unit 18 can inform that whether operating personnel will oneself be associated with network and add network in the in the end remaining open network groove of peripheral unit 18.Therefore, except informing that operating personnel are successfully associated, operating personnel can be apprised of the present fullcharging of this network, and indication no longer includes peripheral unit and can add the current network setting again to.Peripheral unit 18 also is stored in the operation address (OPADR) and the operating walk way (OPCHL) of its gateway assigned I D, gateway 12 in its internal storage in step 66.Process control finishes 54 subsequently.It will be apparent to those skilled in the art that step 63-66 can resequence according to embodiments of the invention.At this moment, device 12,18 is associated, and is converted to the operator scheme (not shown) of the further exchange that data and information wherein may take place.
Refer again to step 44, if current association status is associated with gateway 12 at 68 indication peripheral units 18, then peripheral unit 18 checks that in step 70 disassociation frame is to determine whether gateway 12 is associated with peripheral unit 18.In embodiments of the present invention, peripheral unit 18 obtains its gateway assigned I of being stored in its internal storage D number, and with the assigned I D comparison in the ID part of its assigned I D number and disassociation frame.If be stored in (for example among the SN2) in the peripheral unit 18 assigned I D number coupling 72 disassociation frame assigned I D number, then peripheral unit 18 transmits its transducer local I D number, its timer information and by the number of gateway 12 to the communications slot of its appointment in step 74.If the timer of peripheral unit 18 is section or the interior timer corresponding to gateway 12 of scope at the fixed time, then gateway 12 receives, upgrades and transmits the disassociation frame of this renewal to peripheral unit 18 in step 76.In one embodiment, this communications slot of gateway 12 checking number and peripheral unit 18 are related and the transducer local I write SNACK D number.Gateway 12 also upgrades this disassociation frame by following operation: determines assigned I D number and next idle groove of related with it ID part, upgrades connective marker AT0 and AT1 as required, and the timer information of new gateway 12 more.
In step 78, if the timer of peripheral unit 18 at the fixed time in section or the scope corresponding to the timer of gateway 12, then the gateway disassociation frame of this renewal is explained and verified to peripheral unit 18.For example, peripheral unit 18 its transducer local idents of checking are stored in the SNACK.After this checking, peripheral unit 18 informs that in step 80 this peripheral unit 18 of operating personnel separates with gateway 12.Peripheral unit 18 is also removed any gateway assigned I D that is stored in its internal storage in step 82.The timer of peripheral unit 18 is cleared or forbids in step 83, and peripheral unit 18 enters standby mode in step 84, and peripheral unit 18 does not transmit by wireless communication system 20 during this standby mode and receives message, detects vicinity once more until it.Process control finishes in step 85 subsequently.
Refer again to step 70, if be stored in assigned I D number 86 disassociation frames that do not match in the peripheral unit 18 assigned I D number, then peripheral unit 18 is open to have determined whether communications slot at step 88 decoding connective marker.If there is the communications slot can be with 90, process control proceeds to above-mentioned step 80, informs that this peripheral unit 18 of operating personnel separates with gateway 12, and removes any gateway assigned I D that is stored in the internal storage.If communications slot is unavailable 92, peripheral unit 18 is informed this network fullcharging of operating personnel in step 94, removes any gateway assigned I D that is stored in the internal storage in step 82, and at the timer of step 83 forbidding peripheral unit 18.Process control finishes in step 84 subsequently.It will be apparent to those skilled in the art that step 80,82 and 83 order and step 94,82 and 83 order can resequence according to embodiments of the invention.
Correspondingly, described with reference to figure 3 as mentioned, if current association status indicates this peripheral unit 18 not related with gateway 12, then peripheral unit 18 is attempted making self related with gateway 12.If network opening, promptly, exist and to be used for the open communication groove of communicating by letter with gateway 12, then peripheral unit 18 will self be associated with gateway 12 and become the part of all device cordless communication networks of 18 of communicating by letter with gateway 12, and wherein this association comprises peripheral unit 18 self is assigned to this open communication groove.If the network fullcharging promptly, does not exist to be used for the open communication groove of communicating by letter with gateway 12, then peripheral unit 18 keeps separating with gateway 12 and does not form the part that all of communicate by letter with gateway 12 are installed 18 network.
On the other hand, if current association status indication peripheral unit 18 is related with gateway 12, then peripheral unit 18 is removed self and self is separated with gateway 12 from being installed 18 network with all of gateway 12 communications.If peripheral unit 18 determines that from disassociation frame gateway 12 is associated peripheral unit 18 with it and in wireless network, then 12 communications separate peripheral unit 18 with collaborative peripheral unit 18 with gateway 12 with gateway.If peripheral unit 18 determines that from disassociation frame gateway 12 is not related with it and not in wireless network, then peripheral unit 18 separates self with gateway 12, and does not communicate by letter with this gateway 12 with peripheral unit 18.
